chin chang » chain change, china zhang, colin chang
lang yang » wang yang, yang yang, lang lang
wang wong » wang yong, wang hong, wang yang

• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((lang yang) OR (ylang ylang)) yi ((chin chang) OR (china chang)) wang wong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((lang yang) or (ylang ylang)) yi ((chin chang) OR (china chang)) wang wong yue ;*".
